A Survey on Identity-Based Blind Signature

Blind signatures are well-studied building blocks of cryptography, originally designed to enable anonymity in electronic voting and digital banking. Identity-based signature were introduced by Shamir 1984 gave an alternative prominent Public Key Infrastructure. An identity-based blind ( $$\textsf{IDBS}$$ ) allows any user interact directly with the signer without prior interaction a trusted authority. The first has been proposed 2002 several schemes since then. Seeking for full comparison these primitives, we propose survey on list all such primitives that seems maintain some security. We also classify their security assumptions based existing expectation have not formalized yet literature. Moreover, empirically evaluate complexity operations used those modern cryptographic libraries. This us perform realistic evaluation practical complexities. Hence, can compare terms size.
